  • subset_blocks(op, n; mode) returns the projectors of n subsets of the views and the data indices of their views (ranges for consecutive views, index vectors on the projector's device otherwise), for RowBlockOp(subset_blocks(op, n)...).
  • The guide "Ordered Subsets and Normalization" uses RegularizedLeastSquares' OSSART with such blocks instead of its own loop.
  • Until LinearOperatorCollection 2.5 PR and RegularizedLeastSquares 0.17 PR are released, the docs environment points at their development branches via [sources]; these two entries are removed after the releases.

subset_blocks(op, n; mode) returns the subset projectors and the data indices of their views, for a
RowBlockOp of LinearOperatorCollection. The guide "Ordered Subsets and Normalization" uses
RegularizedLeastSquares' OSSART with such blocks instead of its own loop; the docs point at the
development branches of both packages until their releases.
